21-yr-old who stole 5o plus million T-Mobile subscribers data

John Binns , A 21-year-old American has taken responsibility for hacking the second largest American mobile carrier T-Mobile and stealing the data of more than 5.3 crore users, The Wall Street Journal reported.

John Binns claimed that the security of the company was "awful". He further told the publication that he had used an unprotected router to access the personal records of customers.

The hacker who is taking responsibility for breaking into T-Mobile US Inc.’s systems said the wireless company’s lax security eased his path into a cache of records with personal details on more than 50 million people and counting.

T-Mobile has said that data from more than 50 million customers was accessed. Stolen data includes customer names, dates of birth, SSNs, ID cards, and licenses.

Mr. Binns, who since 2017 has used several online aliases, communicated with the Journal in Telegram messages from an account that discussed details of the hack before they were widely known.

The August intrusion was the latest in a string of high-profile breaches at U.S. companies that have allowed thieves to walk away with troves of personal details on consumers. A booming industry of cybersecurity consultants, software suppliers and incident-response teams have so far failed to turn the tide against hackers and identity thieves who fuel their businesses by tapping these deep reservoirs of stolen corporate data.

The breach is the third major customer data leak that T-Mobile has disclosed in the past two years. The Bellevue, Wash., company is the second-largest U.S. mobile carrier with roughly 90 million cellphones connecting to its networks.

The Seattle office of the Federal Bureau of Investigation is investigating the T-Mobile hack, according to a person familiar with the matter. “The FBI is aware of the incident and does not have any additional information at this time,” the Seattle office said in a statement Wednesday.
